Claw Dojo: Claw Machine Sim
Hook Ring Arcade Physics Game
Free · In‑App Purchases · Designed for iPad. Not verified for macOS.
Claw Dojo is a practice simulator for the "hook & ring" style claw machine found in Japanese arcades, built on real rigid-body physics.
HOW IT WORKS
• A ring hangs from a chain. Move it left and back, press DROP, and try to thread the hook mounted on the wooden board to lift the prize.
• Every outcome is decided purely by physics. There is no random roll and no hidden win rate. Your aim and your read of the swinging ring decide everything.
• Drag anywhere to orbit the cabinet 360°. Line up your shot from the side or from above, just like at the real machine.
MACHINE SETUP (all free)
• Set the number, position, size and angle of the hooks, the ring size and the board size.
• Recreate a setup you saw at the arcade and practice it at home.
• 6 cabinet themes: Pop & Cute, Retro Arcade, Neon Tech, Natural Wood, Sunny Pop and Dojo.
PRIZE SHELF
• Collect 14 prizes. Complete a category to reveal its secret prize.
• Collect them all to unlock the grand secret.
COINS
• 1 play = 1 coin. Free coins are granted every day (more with a login streak).
• Watch a short rewarded video to earn extra coins.
• Coin packs and a one-time Unlimited Coins purchase are available.
Prizes are virtual items inside the app. No physical prizes are shipped.
Results are determined by the physics simulation only. There are no random elements or configurable win rates.
